Re: how much?

Im not an engine building expert at all, but I think flat tops are the way to go. If you had domed pistons I believe your compression would be too high.

As far as the rest of the build I have zero idea...except gear drives are cool for awhile, you may tire of the noise (if its a noisy square cut gear one) my brother has one in his 65, cool at first lol.
